Laois and Offaly fall under today's Status Yellow warning coming into effect at noon.
A high temperature warning remains in place in South Leinster and South Munster, including Laois and Offaly.
Met Éireann is warning of extremely dry conditions, with the chance of drought and forest fires.
The warning continues until 8pm tonight.
Alan O'Reilly of Carlow Weather, says one county may reach the previous heatwave record tomorrow:
The National Severe Weather and Flood Coordination Group met today to discuss the impacts of the ongoing period of high temperatures and co-ordinate any cross-sector actions that may be required.
Potential Impacts
• Water safety issues due to increased use of waterways, lakes and beaches
• Some heat stress and dehydration, especially for the vulnerable and elderly
• Potential disruption to public transport
• Animal welfare issues
• Drought concerns
• Wildfires and forest fires
Minister James Browne said:
“This is unreal weather and for so many people it’s exactly what was needed to mark the summer.
“But, and we hate to say ‘but’ when it comes to the sun in this country, it does place additional pressure on many people and certain services like water supplies.
“I am asking again that the public look out for anyone who may need assistance and to heed the advice of the HSE, Met Éireann and your local emergency services and county council updates over the weekend.
“It is hugely disappointing to me that we have seen some major damage due to fire caused by the use of disposable barbecues to Killarney National Park. It’s outrageous. It’s frustrating. It’s entirely avoidable when it’s caused by people like this. There is no excuse in my view. We have to do better here.
“Please be extra vigilant when visting our national parks and remember disposable barbeques are not permitted. I want people to enjoy the sunshine but please do not put yourself or the environment around you in harm’s way.
“Remember when outdoors to wear a hat and stay hydrated. Be extra careful around the sea, our rivers and lakes regardless of your swimming experience or ability - please take care.”
